Hi HowardH,
Seeing this a little late. I have a ERIKA 70, and am a big fan of the pull-push saw concept. Like Mahogany Man, if my van were to be hit by a comet tonight, a new ERIKA would be at the top of my "To-Buy!" list. Top level impressions:
-- Ideal crosscut machine. I sold my Kapex to help cover the cost of the ERIKA, and I haven't owned a miter saw in the last ten years or so, and haven't missed it. I'd say the ERIKA is primarily a crosscut machine, that happens to do a good job at ripping.
-- Dado: I never missed it. If I needed to plow a dado, I'd break out the router table.
-- Miter slot: Don't miss it. The Pull-Push concept negates the need for a miter gauge for cross-cuts, and the Jessem Clear-Cut TS rollers negate the need for feather boards.
-- Service: In my personal experience, the service I've received from Timberwolf Tools is second to none. In the rare cases I've needed tools serviced or repaired, the staff at Timberwolf has been prompt and helpful.
As a side note, the ERIKA saws operate in a manner very similar to format slider saws.
That being said, the ERIKA saws aren't for everyone, and in my mind are ideally suited to mobile, remodeling settings. If the use case is more of a shop-based situation, I'd recommend a band saw and/or small format sliding saw.
Remember, the SS only works after you've made contact with the saw blade. In my opinion, that's too late. To my way of thinking, you'd be better served with a machine and process that prevents blade contact in the first place. Good luck, and be safe out there.
